Description

DESCRIPTION The invention relates to a heat exchanger and a method for producing it. used in apparatus. In such heat exchangers, gas or liquid fuel An ignited burner is provided. The heat created by the flames coming out of the burner is exchanged between the gas and the heat exchange surface of the heat exchanger, from which the heat such as water for central heating given to channels or areas in the heat exchanger transferred to a fluid, air or water for domestic use. This kind of heat During use in heat exchangers, pressure occurs at high temperatures. This is this kind of It requires special requirements in terms of sealing of heat exchangers. It is quite difficult to produce and store the necessary molds for molding the heat exchanger. It is a relatively expensive method as it is expensive. Lost core technology This becomes more apparent when used.

In addition, the heat exchanger of the heat exchanger is mounted with pipes, plates and the like. welding technology for lid stoppers for It is known that it is made by mechanical processes. In this method, especially the assembly steps because it is quite expensive. Different molds are required for different capacities of heat exchangers.

In other words, for the required mold system of such series of heat exchangers large investments are required.

The NL9002201 is a one-piece light metal extruded cylindrical core explains the heat exchanger. A cylindrical copper sleeve is provided around the core. this arm 02048-P-0001 should be fitted tightly. Conduction of a heated gas within the core within the core Two concentric fields are provided to form the field. The two fields in question In the outer one, close to the arm, four water transmission channels are provided. In one arrangement, an upper part of the central part of the core, intended to form a burner area by machining into which a cylindrical burner is inserted is removed. Heated waste from the burner that contacts the heat core during use It is transferred from the gases to the water flowing through the channels.

This type of known heat exchanger is processed by machining in the extruded core. It has the disadvantage that it is very difficult to supply the burner area. And also, The effective surface for heat transfer from waste gases to water is very small. Also, heat after heating the heat exchanger, such as microcracks in the materials areas of waste gas and water, which will cause cracks and leakage of the heat exchanger. thermal stresses inside the core due to temperature differences between the channels. i.e. differences in core and arm expansion, thermal and physical problems will appear. In particular, heating and/or cooling the core and arm A gap may occur between the outer surface of the core and the inner surface of the arm during leads to energy inefficiency and, for example, penetrating around the heat exchanger which may spread to the environment due to unwanted fumes and at a later stage, dangerous for public health due to possible accumulation of dirt such as soot in between it can be too. These problems are caused by such heat exchangers as 4 bar or higher or even 10 bar. and above, it increases even more than it should be able to withstand high pressures, with this However, in some test operations this pressure may be even higher.

Another disadvantage of a heat exchanger according to NL90022017 is that the arm is not provided. is needed. This makes it easy to fit tightly around the relatively long core. on its own due to the use of copper as well as being unusable is costly. Also, an extrusion for a core of this type of heat exchanger The mold is expensive and requires a lot of maintenance.
